Question

Which graph represents an odd function?

Answer 1

Answer: the origin

Explanation:

if the function is odd the graph is systematical about the origin.

Answer 2

The graph of an odd function will be symmetrical about the origin. For example, f(x) = x3 is odd. That is, the function on one side of x-axis is sign inverted with respect to the other side or graphically, symmetric about the origin.
